Civil engineering is a professional engineering discipline that dealswith the design, construction, and maintenance of the physical andnaturally built environment, including public works such as roads,bridges, canals, dams, airports, sewage systems, pipelines, structuralcomponents of buildings, and railways. is traditionally broken into anumber of sub-disciplines?? It is considered the second-oldestengineering discipline after military engineering, and it is defined todistinguish non-military engineering from military engineering. Civilengineering can take place in the public sector from municipal publicworks departments through to federal government agencies, and inthe private sector from locally based firms to global Fortune500 companies. ???Determine the coefficient of permeability of a confined aquifer 8 m thickwhich gives a steady discharge of 25 litres/sec through a well of 0.5 m radius.The height of water in the well which was 20 m above the base beforepumping dropped to 7 m. Take the radius of influence as 350 m.Civil is the application of physical and scientific principles for solvingthe problems of society, and its history is intricately linked to advancesin the understanding of physics and mathematics throughout history.Because civil engineering is a broad profession, including severalspecialized sub-disciplines, its history is linked to knowledge ofstructures, materials science,geography, geology, soils, hydrology, environmentalscience, mechanics, project management, and other fields.Please give the accurate, handwritten and correct answerfor good rating

A fully penetrating well with diameter of 0.25 m is bored into an unconfined aquifer with hydraulic conductivity of 22 m/d and porosity of 0.3. The water table is initially at a height of 55 m above the bottom of the aquifer. After continuous pumping, a steady state drawdown of 12 m is reached. (a) If the pumping rate has no effect on the water table at a distance of 1.2 km from the pumping well, determine the pumping rate. Determine the drawdown in an observation well 600 m away from the pumping well. Determine the travel time from the observation well to the pumping well.
Could you help me answer the following question? Thank you A fully penetrating pumping well extracts groundwater from a confined aquifer with a pumping rate of 750 m3/day. The hydraulic conductivity of the aquifer is 10 m/day and the saturated thickness is 50 m. The drawdown of the aquifer from this pumping well is insignificant at a distance of 1000 m from the pumping well. At what distance from the pumping well is the drawdown 10 cm? Assume the hydraulic gradient is negligible in the local area. Transmissivity T = 1746.76 gal/min/ft Hydraulic conductivity = 11.645 gal/min/ft2 Storativity = 0.809 The drawdown on Jenny’s Well by the end of August. =0.6902 ft. Observation well situated is 69.7 ft away from the pumping well (which is pumping at the rate of 305 gal/min). The aquifer is confined, and the depth has been measured from well logs and is 150 ft. The data for time (t) and drawdown (s) is given below: t (min) s (ft) 0.072 0.003 0.105 0.006 0.155 0.012…
Find the corresponding hydraulic conductivity of aquifer when discharge 3 through the aquifer is 1500 m³/day. The length and width of the aquifer normal to the discharge direction is 10,000 m and 1500 m respectively. 300 m and 250 m are the hydraulic heads at the entry and exits points of aquifer respectively.
Please solve,.
A confined aquifer with T = 7.0 x 10-3 m2/s and S = 5 x 10-4 is pumped by two wells, 35 m apart. One well is pumped at 7.6 L/s and one at 15.2 L/s. Plot the drawdown h0-h versus distance along a line joining the wells, 4 hours after the start of pumping. Use 5 m increments along the line. How would I go about this question if my initial r1 would equal 0 and and r2 would equal 35m additionally how would I get the pumping rates at each 5 m increments. overall please give a step by step on how I Would go about this question
What is the pumping rate (in m°/d) required to create a drawdown of 129 mm at 173.7 from the well after 25 days of pumping. The aquifer is confined, and is 42.9 m thick and has a K of 13.8 m/d. Take the specific storage as 1.7E-6 1/m.
9.An unconfined aquifer with K-30 m/day is bounded by a stream on one side as shown in Figure 2, At a distance of 80 m from the stream, a well of 0.4 m diameter is pumped at rate of 3000 m³/day. What is the drawdown in the well? Q=3000 m³/day 20 m m 801 Figure 2 C C d=0.4 m K=30 m/day Impermeable Layer m³ / day
A well in an unconfined aquifer is pumped at the rate of 50 L/s ( 800 gal/min.). The thickness of the aquifer is 30 m. and the elevation of the phreatic surface is 25 m. above the underlying aquiclude at an observation of well 20 m away from the well and 34.6 m above at a well 50 m. away. What is the value of K for this aquifer?
